Heat Fluid - Graco XM Series Operation

Recirculate

Heat Fluid

To heat fluid evenly throughout the system:
1. Circulate fluid at approximately 1 gpm (10-20
cycles/min.) to raise temperature of hoppers to
80-90° F (27-32° C).
2. Decrease circulation rate to approximately 0.25 gpm
(5 cycles/min.) to increase the heater outlet
temperature to match the spray temperature.

NOTE: Circulating fluid too quickly without decreasing
the circulation rate will increase only the hopper
temperature. Similarly, circulating fluid too slowly will
increase only the heater outlet temperature.
NOTE: Agitate, recirculate, and heat material only as
necessary to avoid mixing air into the fluid.
